Negative.

1. The reason why online loan interest will not keep getting higher is that the loan agreement usually clarifies the interest rate and repayment period. The interest is determined in the contract and will not increase over time. Even if there is a late payment, penalty interest will generally be charged according to the contract, but this does not mean that the interest rate will continue to increase.

2. Online loan platforms usually conduct credit assessments on borrowers and determine interest rates based on their credit ratings. Therefore, the borrower's repayment ability and credit profile are the main factors affecting interest rates, rather than the passage of time.

3. In China, the online lending industry is subject to supervision by regulatory agencies, including the setting of interest rate ceilings. According to relevant policies, the interest rates of various online loan products have clear upper limits to protect the rights and interests of borrowers.

To sum up, online loan interest rates will not get higher and higher. Interest is determined in the contract and is subject to regulatory oversight. The credit status of the borrower is a key factor in determining interest rates, and the passage of time does not directly lead to an increase in interest rates.
